Default Error "timecounter TSC must not be in use when changing frequencies; change denied"
Hello all,

I had a Pentium-4 based system running FreeBSD 7.0. 7.0 when installed when it was released; till 7.1 I did not perform any cvsup upgrade operations.

On 7.0 I had cpufreq enabled in kernel:
Code:
device cpufreq
Additionally, powerd was enabled in /etc/rc.conf:
Code:
powerd_enable="YES"
With those in place, my system cpu succesfully changed frequency, according to system load. Some dev.cpu variables are listed below:
Code:
dev.cpu.0.%desc: ACPI CPU
dev.cpu.0.%driver: cpu
dev.cpu.0.%location: handle=\_PR_.CPU0
dev.cpu.0.%pnpinfo: _HID=none _UID=0
dev.cpu.0.%parent: acpi0
dev.cpu.0.freq: 374
dev.cpu.0.freq_levels: 2999/-1 2624/-1 2249/-1 1874/-1 1499/-1 1124/-1 749/-1 374/-1
dev.cpu.0.cx_supported: C1/0
dev.cpu.0.cx_lowest: C1
dev.cpu.0.cx_usage: 100.00%
Compared to the kernel I had in place, the only changes I did are the additions of the following lines:
Code:
options 	SCTP	# Had it disabled in 7.0
Finally some more info from the running system:
Code:
# uname -a

And in the last lines lies my problem. After the switch to 7.1, my system can not switch operating frequencies. The "timecounter TSC..." errors fill up my system logs.


I can see that this line is produced by the tsc.c source file. From the same source code it seems that when the timecounter is TSC, frequency changes (by cpufreq for example) are prohibited. What buffles is me is why this used to work perfectly in 7.0! Was it that another clock source was used back then? BTW, ntpd had been running since the days this system had FreeBSD 4.0 on it...

Any information provided will be appreciated.

Alas, the forum has a character limit per post so I split info, but in the process I failed to mention why this problem arised. And I can't edit my first post. So I'm writing it here:

"In the last few days I've upgraded to 7.1. On 7.1 I did not switch to the new ULE scheduler, I sticked with the old one. Also note that the SMP option is missing, as well as a lot of networking options and the like." (Note the current 7.1 kernel config is in the previous post, above)"

Default Error "timecounter TSC must not be in use when changing frequencies; change denied"
I am using PCBSD with KDE, if that means anything.
Also, the error "timecounter TSC must not be in use when changing frequencies; change denied" appears in the terminal after I click the log out button. I just installed gnome, and was wanting to try it. Is there a way I can fix this problem, or another way to switch to using gnome?

Hello there
I know this thread is over a year old, but I just cought the same problem and I found a solution. Original thread author probably don't need it anymore, but google showed me this topic at first place, so maybe someone else will find my solution useful.

At the beginning check output of:

Code:
# sysctl kern.timecounter.choice
It will show you timecounters available on this machine.
In addition

Code:
sysctl kern.timecounter.hardware
will show you which one of them FreeBSD choosed to use. By default it should be the one with highest number between brackets (higher number = higher TC quality). Here's example output of my system:

Code:
kern.timecounter.choice: TSC(800) i8254(0) dummy(-1000000)
kern.timecounter.hardware: TSC
If TSC has highest number and we want to use powerd on the same machine, we should manually force different choice, because TSC seems to be based on fixed CPU frequency. Probably best choice will be the second one with highest number, i8254 in example above.

So whole solution in this case is:

Code:
# sysctl kern.timecounter.hardware=i8254
# echo "kern.timecounter.hardware=i8254" >> /boot/loader.conf
Now powerd works like a charm.

p.s. With low quality rated timecounter you should also consider running ntpd besides powerd.

Thank you for this info. It has worked a treat for me also.

If I could ask a question please [newbie here]: when I reboot the server the error comes back up. Is there a way I can hardcode this in or get it write during system startup at all?

Thanks but ncpnc has already posted that information.

I have the embedded installation, as far as I can see it needs to go to /cf/boot/loader.conf but when I add the value to that file it is not liked at all.

Hi, sorry to revive an old topic, but I am having the same issue. I can temporarily solve it using the following command (through the WebGUI):
sysctl kern.timecounter.hardware=i8254

This solves the issue, and then allows the CPU frequency to drop (from 2900Mhz to 730Mhz). I have manually edited and saved the /cf/boot/loader.conf (as I am running embedded) and added the line:
Code:
kern.timecounter.hardware=i8254
I was hoping this solves the issue, so that the error doesnt come up every time the NAS is booted. But instead, nothing happens.. I also noticed if I turn off "power daemon" in advanced settings, the error doesnt come up (because its not trying to change the frequency). Am I missing something in getting this working?

Never mind, I worked it out.. Here's how:

I had to place the code:
Code:
kern.timecounter.hardware=i8254
in /etc/sysctl.conf.

To do this (as I am running FreeNAS.. go to "System --> Advanced --> sysctl.conf, and add in the code there.

Works a charm on embedded installations; and now my 2.93GHZ Celeron clocks down to 700Mhz pretty much all the time. CPU temps have dropped 2 degrees too (passive cooling)
